In Qt's QMake pro files, how can I differentiate between android for 32-bit arm and android for 64-bit arm?

Question

In a Qt .pro file, I can distinguish between android and windows like:

linux:android {
  LIBS += -L[...]
}

win32 {
  LIBS += -L[...]
}

How can I distinguish between android for 32-bit ARM platform aka armeabi7v and anddroid 64-bit ARM aka aarch64.

How can I specify aarch64 or armeabi7v in the pro file?

Answer 1

Apparently QT_ARCH tells me more, which leads to:

android:contains(QT_ARCH, arm) {
  message("arm32!");
}

android:contains(QT_ARCH, arm64) {
  message("arm64!");
}
